The BitCurator Access project developed tools to help libraries, archives, and museums provide web-based and local access to born-digital materials held on disk images. BitCurator Access tools simplify access to raw and forensically-packaged disk images, allowing users to incorporate these objects into access environments while preserving original order and relevant environmental context. Using open source digital forensics software libraries, these tools enable detailed analysis of file and file system provenance, quality and accessibility of files, metadata in files and the file system, and residual or hidden data.

BitCurator Access focused on four areas of interest related to accessing born-digital collections:

Web-based access to raw and forensically packaged disk images

Redaction of file items, metadata and hidden data from disk images

OS and executable virtualization for legacy disk images

Transforming and using digital forensics metadata in collecting environments

The bitcurator-access-webtools project is a Flask application that allows users to browse file systems in raw and forensically packaged disk images within a web browser. The application can parse raw and E01-packaged images containing FAT16, FAT32, NTFS, HFS+, and EXT 2/3/4 file systems, and allows users to navigate the file system contents, download individual files, and search the contents within a simple web interface.

Virtualized Access Environments

Born-digital materials that contain executable content or bootable operating systems often require virtualized hardware support to remain accessible. Between 2014 and 2016, the BitCurator Access project explored a range of methods to provision virtual machines providing access to disk images extracted from legacy media, including the use of the bwFLA Emulation-as-a-Service platform developed at the University of Freiburg.
